Last month, AMD announced its Radeon HD 8000 series would arrive this year, just not until the tail end of it. Bridging the gap would be more HD 7000 series cards, including new versions to presumably cater to all price points. At the time AMD wasn't ready to say just what those new HD 7000 series cards would be like, but now it looks like we have an idea of at least one. Now this isn't official from AMD as all we have to go on are leaks, but it sounds pretty accurate. Next month will see the AMD Radeon HD 7790 launch, which aims to fill the void between the 7770 and the 7850. This new card supposedly has 786 shader processors, a clock speed of 1075MHz, and 2GB of GDDR5 memory on a 128-bit bus. It'll support DirectX 11.1 and OpenGL 4.3, but performance comes in about 10% less than an HD 7850.

Interestingly, the HD 7790 features a 28nm Bonnaire XT chip and uses the Graphics Core Next (GCN) 2.0 architecture. That component should be appearing in the HD 8000 series, so perhaps the 7790 is a sneak preview of what's to come later this year. That is, of course, if the rumor holds true. We'll find out in April one way or the other. The HD 7790 is expected to be priced in the $150-180 range.

I have a pair of 7770s in crossfire now. They just are not quite enough to power some of my games properly, but they are OK. Maybe these 7790s will do the trick without breaking the bank.
